所以透明外面罩必須具備優(yōu)異的耐光性能，不變黃，不龜裂，同時還要保持良好的透光度，且耐刮擦。PC材料雖具有一定程度的耐光性能，但是若要求長時間的戶外使用，其耐候性仍然不能滿足使用要求；另外，其表面硬度較低，鉛筆硬度只有1～2H等級，在使用過程中容易擦傷，刮花，從而影響透光效果，因此在汽車外部燈具外面罩使用傳統(tǒng)透明PC材料時，必須在PC外面罩上噴UV漆后才能滿足該產(chǎn)品的相應(yīng)要求。但傳統(tǒng)PC面罩外噴UV漆這種工藝，存在以下問題。存在問題1、對于可直接噴涂UV漆的面罩，噴涂會導(dǎo)致燈具材料成本的增加以及生產(chǎn)線投資、維護成本及人工成本的增加；2、對于透明PC材料和其他材料雙色注塑成型這種設(shè)計，若只在面罩的PC部分噴涂UV漆，UV漆邊界難以控制（特別是對于大尺寸、易變形的零件），影響外觀效果，且會導(dǎo)致廢品率增加；非噴涂部位需遮擋掛具，且對掛具精度要求較高，導(dǎo)致生產(chǎn)成本增加；若面罩和其他部分全部噴涂UV漆，因不同的材料特性，會導(dǎo)致零件的不同材料區(qū)域外觀、性能差異/缺陷，尤其是長時間使用后差異/缺陷更明顯；對其再進行其他工藝處理時，會導(dǎo)致處理后面罩的質(zhì)量下降，甚至因UV漆的存在，無法實現(xiàn)其他工藝處理，比如對多組份面罩噴涂UV漆后。</p><p> PC基礎(chǔ)創(chuàng)新塑料(美國)DCL-4033聚碳酸酯聚碳酸酯（英文簡稱PC）是分子鏈中含有碳酸酯基的高分子聚合物，根據(jù)酯基的結(jié)構(gòu)可分為脂肪族、芳香族、脂肪族－芳香族等多種類型。其中由于脂肪族和脂肪族－芳香族聚碳酸酯的機械性能較低，從而限制了其在工程塑料方面的應(yīng)用。*有芳香族聚碳酸酯獲得了工業(yè)化生產(chǎn)。由于聚碳酸酯結(jié)構(gòu)上的特殊性，已成為五大工程塑料中增長速度**快的通用工程塑料。成分聚碳酸酯是一種強韌的熱塑性樹脂，其名稱來源于其內(nèi)部的CO3基團?？捎呻p酚A和氧氯化碳（COCl2）合成。現(xiàn)較多使用的方法為熔融酯交換法（雙酚A和碳酸二苯酯通過酯交換和縮聚反應(yīng)合成）。雙酚A和碳酸二苯酯反應(yīng)原理：性質(zhì)化學(xué)聚碳酸酯（PC）是碳酸的聚酯類，碳酸本身并不穩(wěn)定，但其衍生物都有聚碳酸酯一定穩(wěn)定性。按醇結(jié)構(gòu)的不同，可將聚碳酸酯分成脂族和芳族兩類。脂族聚碳酸酯。如聚亞***碳酸酯，聚三亞甲基碳酸酯及其共聚物，熔點和玻璃化溫度低，強度差，不能用作結(jié)構(gòu)材料；但利用其生物相容性和生物可降解的特性，可在***緩釋放載體，***縫合線，骨骼支撐材料等方面獲得應(yīng)用。聚碳酸酯耐弱酸，耐弱堿，耐中性油。聚碳酸酯不耐紫外光，不耐強堿。PC是一種線型碳酸聚酯。PC

時間至少4小時以上;2.注射溫度注射溫度必須綜合制品的形狀、尺寸、模具結(jié)構(gòu)、制品性能、要求等各方面的情況加以考慮后才能作出。一般在成型中選用溫度在270~320℃之間，過高的料溫如超過340℃時，PC將會出現(xiàn)分解，制品顏色變深，表面出現(xiàn)銀絲、暗條、黑點、氣泡等缺陷，同時物理機械性能也下降。PC溫度很敏感，熔體粘度隨溫度升高而明顯下降，料筒溫度250~320℃.(好不要超過350℃)，適當(dāng)提高料筒溫度對PC塑化有好處。必要時內(nèi)應(yīng)力退火，烘爐溫度125~135℃，時間2小時，自然冷卻到常溫。3.注射壓力對PC制品的物理機械性能，內(nèi)應(yīng)力、成型收縮率等有一定的影響對制品的外觀及脫模性有較大的影響，過低或過高的注射壓力都會使制品出現(xiàn)某些缺陷。一般注射壓力控制在80-120MPa之間，對薄壁，長流程，形狀復(fù)雜，澆口較小的制品，為克服熔體流動的阻力，以便及時充滿模腔，才選用較高的注射壓力(120-145MPa)，從而獲得完整而表面光滑的制品。流動性差，需用高壓注射，但需顧及膠件殘留大的內(nèi)應(yīng)力(可能導(dǎo)致開裂)注射速度：壁厚取中速，壁薄取高速。4.保壓壓力及保壓時間保壓壓力的大小及保壓時間的長短對PC制品的內(nèi)應(yīng)力有較大的影響，保壓壓力過小。沙伯基礎(chǔ)（原GE）玻纖增強，阻燃，脫模性能好，運動器材，高抗沖，**度，照明工具。江蘇哪里的PC銷售廠家</p><p
